Flow regime meaning

WebAug 31, 2024 · A low flow is typically a seasonal phenomenon (e.g., the "dry season") and is an important component of the flow regime in any river or stream. By contrast, a drought is an event that results from an extended period of below average precipitation. While droughts include low flows, a continuous seasonal low-flow event is not necessarily a … WebFlow Regime. From a practical engineering point of view, the flow regime can be categorized according to several criteria. All fluid flow is classified into one of two broad categories or regimes. These two flow regimes are: Single-phase Fluid Flow. Multi-phase Fluid Flow (or Two-phase Fluid Flow) This is a basic classification.
